Failure of one or more of the three E1 lines from HEAnet, Dublin
to MCI, West Orange. (Circuits PLBBVWW5001,2,3).
Two lines were down from approx. 19:00 UTC+1 yesterday until approx
10:10 UTC+1 today, when they were restored by MCI.
Lines were clear until 15:50 when circuit #2 failed.
IMUX backs up transparently onto the remaining lines, so connectivity
is still available although impeded. Currently running at 4Mb.
Fault was in MCI's hands. (Ticket 464/29may)
MCI resolved the problem.
